On a boring weekend, there is still no one to ask for. There is nothing to do, and she ran to the next door. As soon as he entered his house, he heard a melodious saxophone sitting on a sofa and drinking his cappuccino instant coffee, which he specially made for me. It was really a bit intoxicated. I searched for the sound to see where it came from, but I could not find it. Asked him, he smiled guiltily and he got up and walked to the "Eagle's Wings to Swallow the World" map. He pointed to the finger painting and said it was sent here. I was stunned. This is not the painting that Tang Bohu painted for Zhu Zhishan. How can it make a sound? The neighbor said that this is a flat panel audio. You see it is a picture on the surface. It is actually a stereo. Then he introduced me in detail the advantages of the flat panel audio and precautions for use.
The flat panel audio is composed of a sound source input device, a signal amplifier (amplifier), and a speaker. It is a complete system that excites the bending wave in the sounding board by the exciter (driver). After several years of market expansion in the industry, it has been widely used in home theater systems, background music systems, multimedia audio systems, and public broadcasting systems.
The flat speaker is a mural and a speaker, and it is a speaker without a speaker. The sound is sent directly from the screen. Hanging on the wall is a painting. The actual speaker and tablet sound use methods and functions are the same as traditional sound.
â– slim shape, does not occupy space
Due to the special structure of the flat speaker, the formed speaker can be placed in any position. Unlike traditional speakers, the effect of hearing is different due to the different positions.
â– Very good directivity
Speakers that are typically made with conventional speakers have poor directionality. You must stand in front of the speakers to hear the perfect sound, especially the treble. If you stand on the side of the speakers, there may be some background or accompaniment sounds. You can't hear it; if you stand on the back of the speaker, maybe that sweet song has become a voice that you don't want to appreciate. The flat panel speakers do not have the above problems. No matter where you stand, you can enjoy the complete and real sound.
â– High fidelity of sound
Traditionally, a conventional horn is in the shape of a cone. When it vibrates and makes a sound, it often concentrates the sound in the throat, compresses it, and then spreads out. The sound that people hear is a compressed and deformed sound. Flat-panel horns do not suffer from the above problems. People simply listen to too many distorted sounds. When they come into contact with a flat-panel stereo, they will feel very ordinary when they start listening, but they are often deeply affected by their natural performance. attract.
â– less sound attenuation
Traditional speakers, when you get too close you will find that the sound is loud, and when you are a little further away, you feel that the sound is much smaller. The flat panel speakers do not have the above problems. No matter if you are at a short distance or a long distance, there is not much difference in the sound heard.
The installation mainly uses wall-mounted installation. According to the size of the speaker, the position of the suspension in the room is determined, and the wall-hung nail can be hung; the debugging method of the flat-panel audio is the same as the traditional acoustic debugging method.
During the decoration, first slot the wiring, position the speakers and position them, and leave the threads out. Finished large home furnishings ready to install speakers. Positioning speakers, wall holes, hanging speakers, each speaker requires two hooks, need to hit two holes. Hanging speakers, wiring, connecting amplifiers. The amplifier connects to a DVD or TV.
What are the 3 flat panel audio precautions?â— Pay attention to the wiring, the speaker cable from the wire 30CM, the wire is a strong electric, weak and strong together with the interference is easy to produce noise, current sound.
â— The 5.1 surround speakers of the home theater need to hang the TV or the opposite wall of the projection. That is behind the sofa. The speakers are not less than 1.2 meters apart. It is best to be separated by more than 1.5 meters, and the surround effect is good when they are enlarged.
â— 5.1 home theater's three main speakers (left and right channels, the center) need to hang the TV or projection wall, the speakers are separated by more than 20CM.
â— Pay attention to the positive and negative polarity of the speaker and amplifier interface. The five channels of DVDs and amplifiers should not be connected wrongly, and the five channels of speakers and amplifiers can't be wrong.
â— When wiring, pay attention to twisting the thread head and plugging in the interface to avoid noise or current noise in the short circuit of the thread head. In severe cases, the power amplifier will burn out.
â— If you do not know which speaker is ringing, you can touch the speaker's screen with your hand. The speakers in operation will have slight vibration.
For a newly renovated house, it is advisable to install it after a week of renovation to avoid the poor quality of the wall paint. It is easy to react chemically with hand-painted oil paintings or print oil paintings, causing the screen to fade.
